heating elements and the exterior casing. this is just another example of edenpure's working to be the safest heater you can buy for your home, as well as the most efficient. >> looking at alternative sources of heat for my home, when i ran across the edenpure the one thing i liked about it was that it didn't have any direct heat that would set a fire on your furniture, your pets, your family, anything like that. and being a fireman, we run into, several times a year, we run into these space heaters that create fires and burn homes down, cause life damage, property damage. and that was my big selling point on the edenpure, more than even the cost savings, was the safety issue of it. >> so, richard, we know our customers love the safety, but what do they say about the best way to save money using an edenpure? >> ah, well, i found out there are two major ways that adding an edenpure saved them money on their home heating. first, because you use an edenpure exactly where you need the heat, virtually 100% of the heat you pay for is delivered directly to the living area.
